求参数值或取值范围的问题在高中数学学习的过程中比比皆是,并且是我们学习中的一个难点问题,但又是我们必须攻克的难点,因为历年的高考试题中都频繁出现.其中,含参数的指数与对数型函数求参数值或参数范围的问题就是其中一类重要的题型.而处理这类问题的手段与方法又有其独到的一面,故我们很有必要了解与掌握其独到的解决问题的方法.下面给出的三道例题讲述的就是从两个角度来如何处理这类题型经常用到的手段。1指数型函数利用奇偶性获取参数值已知某一个含参数函数的奇偶性,去求该函数的参数值,这 The problem of seeking the value of the parameter or the range of values ​​abounds in the process of high school mathematics learning and is a difficult problem in our study but it is also a difficult point that we must overcome because the college entrance examination papers over the years are frequent. , With the parameter index and logarithmic function parameters or parameter range of the problem is one of the important types of questions and methods and methods of dealing with this kind of problem has its own unique side so it is necessary for us to understand and Master their unique ways to solve the problem.The following three examples are given about how to deal with these types of questions frequently used means from two angles. 1 exponential function using parity to obtain the value of a parameter known to have a parameter function of the parity, to find the function parameter values, which
